PRINTING AND REPRODUCING MACHINE.

Specification of Letters Patent.

Patented Dec. 29, 1914.

To all whom t may concern:

Beitknown that I, BENJAMIN OTTO FANs- Low, of the city of Los Angeles,inthe county of Los Angeles, in the State of California, havevinvented anew or Improved Printing and Reproducing Machine, of which the followingis a full, clear, and exact specification, reference being had to theannexed drawings and to the letters and figures marked thereon.

My said invention relates to a new or 1mproved machine for reproducingcopies of documents, drawings, and pictorial representations, and hasfor its object to effect such reproduction by printing operationsperformed in and by the machine hereinafter described.

The object of my invention is the same as that set forth in myapplication for Letters Patent, Serial Number 362064:, filed March 11th,1907, namely, to attain extreme simplicity in the machine used foreffecting the aforesaid operations, and so that all mechanicalarrangements for retaining the travel of the impression roller in adefinite to and fro course upon the guides or rails of the base of themachine wherein the type or other surface to be printed froin iscarried, and with other appurtenances as hereinafter set forth.

In my improved machine when used for .rinting operations, the lines oftype may e arranged either at right angles to the length, or thedirection of travel, of the impression roller, and the inking ribboninstead of traveling lengthwise of the machine as shown and described inmy aforesaid application for Letters Patent, may move in a direction atright angles to the direction of the movement of the impression roller,or the lines of type may be at right angles to both the direction oftravel o? the impression roller, and the inlring ribbon, in which casethe impression roller and the inking ribbon both travel in the samedirection, that is to say, at right angles to the direction of the linesof type. A loop handle is attached to the axis of the impression roller,which latter is made heavy or of a Weight great enough to press thepaper to be printed upon to the inking ribbon, and the mking ribbon tothe printing surface consisting of type, electro-type, engravings, halftone blocks, or other equivalent printing surfaces.

The impression roller is formed with deep flanges at its ends to runupon parallel guides, one at each side of the machine,v and instead ofthe loop handle, the impression roller may be mounted upon an axle in acarriage, the ends of which carriage are provided with rollers forrunning upon parallel guides or rails at the sides of the machine.

In the accompanying drawings: Figure l is a vertical section on the linea-a, of Fig. 2; Fig. 2 is a top plan view of one form of my machine; andFig. 3 is a side elevation of the machine shown in Fig. 2.

In my new machine as shown in Figs. l and 2, the lines of type A arecontained in the chase B, in the usual manner, by the toothed wedges Cand D, respectively, operated by a galley-key in the ordinary manner,and the chase B, with the types A fastened therein, rests upon the flattop surface of the base A of my machine.

The impression-roller E is formed with flanges F and G, at each endthereof, respectively, vvhich engage with the rails or guides H, H,attached adjustably to each side of the base A. Rising up from the baseA are four bearing-blocks I, which contain the bearings for theinking-ribbon rollers K, K, so that the inking-ribbon rollers are inposition parallel to the rails or guides H, H, and at right-angles tothe axis of the impression-roller E. The angular direction of movementsof the impression-roller E and the inking ribbon rollers K, K, aretherefore at right-angles to each other, While the travel of theinking-ribbon L is at right-angles to the direction of travel of theimpression-roller E relatively to the frame, and at right-angles to thelines of type A, A, contained in the chase B; whence it follows that,while the impression-roller E travels over the lengths of each line oftypes A, it simultaneously travels over the width of the inking-ribbonL, as shown at Figs. 1 and 2. The im ressionroller E is provided Withtwo tapolts M, M, which are screwed into its center, as shown at Figs. 1and 2, and which, when in place, constitute the bearings for the loop N,which also constitutes the handle whereby when taken hold of by the handthe im ression roller E, may be traversed to an fro upon the parallelrails or guides H, H, and to press the paper situated between the lowerpart of its surface` and the upper surface of the inking ribbon L, andthe inking ribbon L, down upon the types A, A.

The loop N, is provided with a pair of supporters 0, one of which isshown at Fig. 3, by which part of the loop rests upon the upper surfaceof the adjustable rails or guides H, and maintains the loop N, inconvenient operative position. As the operative surfaces, namely, theuppei edges of the guides or rails H, H, may from time to time requireadjustment so as to insure that the cylindrical surface of theimpression roller E, is perfectly true, level and coincident with theupper surface of the types A, or other printing or impression surfaceplaced in the chase B, the rails H, are constructed with inclined slotsI), P, P, as Shown at Ir ig. 3, through which the tap bolts Q, Q, Q,Figs. 1, 2, and 3, pass. At one end of each of the rails or guides H,the point of the adjusting screw R, is pressed into contact with theadjustable rails H, being each carried in the lugs S, so that by turningthe adjusting screws R, in either direction, each of the rails or guidesH, is moved longitudinally and rises upward or downward accordingly withthe direction in which the adjusting screws It, are turned, and therebythe rela.- tionship of parallelism and closeness of contact of theimpression roller E, with the inking ribbon L, the types A, and thepaper carried thereon, is capable of being adjusted with the utmostprecision from time to time as required. Each adjusting screw R, isprovided with a check nut R, for holding the adjusting screws in anyposition required, as is well understood. As at each printing operation,a length of the printing ribbon L, equivalent to the length of the rowsof types, that is to say, from the outermost row B, to the outermost rowB2, moves it follows that a. fresh surface of printing ribbon L,corresponding to whatever may be the distance between the outermost rowsof type B', and B2, respectively, 'is necessarily required to be drawnover the type for each successive printing operation, therefore it isessential that a quantity or length of the printing ribbon L, shall bewound off one of the ribbon rollers K, and on to the other of the ribbonrollers K, during the interval between each two printing movements oroperations of the impression roller E. For this purpose the outer endsof the axles of each of the ribbon rollers K, is provided with a crankhandle U, by turning either of which, the requisite length of unusedprinting ribbon L, is wound off one of the printing ribbon rollers K,and on to the other printing ribbon roller K. The inking ribbon passesover the types A, and on to the printing ribbon rollers K, K, in thedirections as shown in section in Fig. 1.

In my invention, it will be noted that the ribbon-supporting means arearranged on the surface of the base of the machine at opposite endsthereof and between the guiderails and chase in which the composition isheld, and that the ribbon-sujiiporting means or bearing-blocks I, forthe rollers K, K, of the inking-ribbon, are not sufliciently cX- tensiveto cause the inking-ribbon upon the rolls to extend above the surface ofsaid guide-rails. In other words, the ribbonsupporting means arearranged at opposite ends of the frame between the guide-rails andcomposition and below the surface of said rails. This arrangement ofparts is particularly for the purpose of maintaining the ribbon-rollersand supporting means out of the way of the rails and theimpressionroller in the travel of the latter over the composition. Andthis position is, of course, maintained notwithstanding adjustments ofthe rails as hereinbefore set forth.

l. In combination with the bed of the machine having parallelguide-rails, a flat composition arranged between said rails, animpression-roller having means at its opposite ends cooperating with thesaid guide-rails to prevent the roller from having endwise movementrelatively to the bed, a loop journaled upon the impression-roller,depending arms carried by said loop and coperating with a fixed part ofthe lnachine for supporting the loop in operative positlon, and lneanson opposite portions of the bed between the composition and rails forsupporting a ribbon in coperative relation to the impression-roller.

2. In combination with the bed of the machine having parallelguide-rails, an 1inpression-roller having means at its opposite endscooperating with said guiderails whereby to prevent endwise movement ofthe latter relatively to the bed, a loop journaled upon the said roller,means carried by the loop for coperating with the said guiderailswhereby to support the loop in operative position, and means carried onopposite portions of the bed for supporting a` ribbon in coperativerelation to the impressionroller.

In testimony whereof, I have hereunto set my hand and seal at the cityof Los Angeles, in the county of Los Angeles, and State of California.,in the presence of two subscr1bing witnesses.
